This paper considers the stability analysis of periodic Takagi-Sugeno fuzzy models. For this we use a switching Lyapunov function defined at the time instants when the subsystems switch. Using the developed conditions we are able to prove the stability of periodic TS systems where the local models or even the subsystems are unstable. The application of the conditions is illustrated on numerical...
The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...
Dry-friction oscillators are mechanical systems with dry friction and stick-slip vibrations. In the context of control theory, the stability analysis of this type of dynamical systems is important since they exhibit non-smooth bifurcations, or most famously a sliding-grazing bifurcation inducing abrupt chaos. This paper develops a Lyapunovbased framework to study the so-called structural stabil...
in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...
Herein, we investigated the effects of active layer thickness (tS) on electrical characteristics and stability high-mobility indium–gallium–tin oxide (IGTO) thin-film transistors (TFTs). IGTO TFTs, with tS values 7 nm, 15 25 35 50 were prepared for this analysis. The drain current was only slightly modulated by gate-to-source voltage, in case TFT = nm. Under positive bias stress (PBS), TFTs a l...
The nudged-elastic band (NEB) method is modified with concomitant two climbing images (C2-NEB) to find a transition state (TS) in complex energy landscapes, such as those with a serpentine minimal energy path (MEP). If a single climbing image (C1-NEB) successfully finds the TS, then C2-NEB finds it too. However, improved stability of C2-NEB makes it suitable for more complex cases, where C1-NEB...
BAckground Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer ...
We performed biomechanical comparison of a xenograft bone plate-screw (XBPS) system for achieving cadaveric lumbar transpedicular stabilization (TS) in dogs. Twenty dogs' cadaveric L(2-4) lumbar specimens were harvested and their muscles were removed, but the discs and ligaments were left intact. These specimens were separated to four groups: the L(2-4) intact group as control (group I, n = 5),...
Two phosphate modifications were introduced into the DNA backbone using Staudinger reaction between 3’,5’-dinucleoside ?-cyanoethyl phosphite triester formed during synthesis and sulfonyl azides, 4-(azidosulfonyl)- N,N,N -trimethylbutan-1-aminium iodide (N+ azide) or p -toluenesulfonyl (tosyl Ts) azide, to provide either a zwitterionic phosphoramidate with N+ modification negatively charged for...
